Last month the Senate Foreign Relations Committee passed the Department of State Authorities Act, Fiscal Year 2018, part of which would effect a major change in the law of foreign affairs appointments. With Congress’s summer recess now coming to an end, it’s worth considering the constitutionality of the proposed change and contemplating the Trump Administration’s potential response.

The key provision concerns ad hoc diplomats. Section 301 would require the Senate’s advice and consent for the appointment of “any Special Envoy, Special Representative, Special Coordinator, Special Negotiator, Representative, Coordinator, or Special Advisor.” On my reading, accompanying language suggests that this requirement would apply regardless of whether the positions in question already exist, regardless of whether Congress has authorized them by statute, and regardless of whether appointments have already occurred. As an enforcement mechanism, Section 301 would bar the obligation or expenditure of funds for any covered position to which an appointment is made without advice and consent. The only exception is for positions that extend for short periods of no more than six months and are certified by the Secretary of State as “not expected to demand the exercise of significant authority pursuant to the laws of the United States.”

This strikes me as a pretty big deal. Anytime the President seeks to designate an envoy to address a pressing issue, he would have to obtain the Senate’s approval. The Senate would thus be statutorily positioned to vet a whole new class of nominees, scrutinize and publicly debate the policies these individuals will implement, and, in extreme cases, block appointments that appear problematic. An optimistic take is that such an arrangement would promote meritocracy and encourage greater deliberation in the use and selection of ad hoc diplomats. The more pessimistic view is that Senate involvement would interfere with the conduct of foreign relations by introducing an additional source of delay and partisanship.

Whatever one makes of the practical merits of Section 301, there’s a sensible constitutional objection: Article II confers on the President the power to conduct foreign relations, the executive branch has invoked this power to justify a common practice of unilateral diplomatic appointments, and Congress has largely acquiesced. Indeed, ever since the Foreign Service Act of 1980, Congress has expressly accepted that the President may appoint envoys without advice and consent for special missions of up to six months in duration, as long as the President notifies the Senate Foreign Relations Committee in advance. In purporting to end this practice, Section 301 arguably violates the separation of powers.

But there’s also a reasonable response. As I’ve argued elsewhere, considerable evidence suggests that the Framers understood ad hoc diplomats such as treaty negotiators and special envoys to be “public Ministers” and “Officers of the United States” within the meaning of the Appointments Clause, without regard for title or duration of service. This understanding appears to have drawn heavily upon the definition of “public ministers” under the historical law of nations and to have influenced the official practice of the Washington, Adams, and Jefferson administrations, each of which repeatedly sought and obtained the Senate’s advice and consent for these kinds of appointments.

The response, in short, is that Section 301 is more or less redundant with the Framers’ understanding of the Appointments Clause itself. Thus, the central issue is not whether the provision is constitutional under any conceivable modality of constitutional argument, but instead whether to privilege the modality under which 301 is likely constitutional over those under which it might not fare so well, in particular historical gloss. That is an issue for the political branches to resolve, but I think it’s worth noting that there’s a plausible case for Senate involvement even in view of contemporary values and concerns. A requirement of advice and consent would make it harder, for example, for the President to delegate critical diplomatic functions to family members who lack experience in international relations. It could also help to provoke public discussion about the merits of the policies the President seeks to advance and discourage initiatives that lack popular support.

At this point, it’s hard to say what will come of Section 301, but in one sense its timing seems propitious. Earlier this week, Secretary of State Rex Tillerson announced a significant reorganization of the State Department’s 66 special envoys. Some of them will take on broader roles, but many of their positions will cease to exist, with the work either assumed by the Department’s regional and functional bureaus, incorporated into the responsibilities of other officials, transferred outside of the Department, or terminated altogether. The Secretary anticipates that these changes will eliminate organizational redundancies and reduce costs. Whether or not that is true, the changes raise an important question: will an administration that appears to view special envoys with uncommon disfavor object if the Senate seeks to play a larger role in the process by which envoys are appointed? Maybe, but the position of the current President seems harder to predict than that of his predecessors.
